Title: Magnetic recording device and magnetic reproducing device
Inventor: SHUDO KATSUYUKI
IPC: G11B20/10
Filed: 1999-10-25
Abstract: PROBLEM TO BE SOLVED: To well reproduce information data words including binary data with a simple circuit even if these data words are recorded in linear tracks and even during traveling in a reverse direction. SOLUTION: The recording waveform of bit data '0' comprises high level=1: low level=3 in duty ratio and the recording waveform of bit data '1' comprises high level=3: low level=1 in duty ratio. The recording wavelength of a tail mark TM indicating the delimiter of the words comprises high level = 1: low level=1 in duty ratio. If these waveforms are recorded in the linear track T2 at the same period by inverting the magnetization direction at a rise and fall, the phase at the rise of the signal during forward traveling (the fall during reverse traveling) is made constant.

Abstract: PURPOSE:To prevent the deterioration in the picture quality caused due to the operation of a dropout compensation circuit by providing a signal level discrimination means applying switch control to a changeover means when a level of a video signal is a prescribed level or over based on a black level. CONSTITUTION:When a dropout is detected by a dropout detection circuit 16, a video signal level discrimination circuit 30 compares a reference level VR with a video signal level V1 just before the occurrence of dropout. In case of V1>VR, a control signal 104 is outputted to a switch SW1 to throw the contact from the position of a contact (b) to the position of a contact (a). An FM video signal from a magnetic head 12 is subject to interporation of dropout occurrence part by a dropout compensation circuit 18 via an amplifier 14 and the result is given to an FM demodulation circuit 20. The video signal processing circuit 22 fetches the demodulated output of the circuit 20 and applies conversion processing to a composite video signal of a prescribed format. In giving a conversion processing end signal 108 to the discrimination circuit 30, the circuit 30 throws the switch SW2 from the position of the contact (b) into the (a) and a video whose dropout is compensated is outputted from the processing circuit 22 to a monitor television 50.

Title: Method and apparatus for computing speed of fluid
Inventor: GORDON JENNINGS
IPC: G01S15/58
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which the speed of a fluid can be computed with high reliability and with high accuracy by a method wherein, when the phase difference between a signal which is inphase and a signal which is at a quadrature phase is neither +90 deg. nor -90 deg. anticipating a prescribed error value, their spectral components are regarded as noises so as to be removed before an average flow velocity is computed. SOLUTION: In the Doppler shift which is generated in a fluid 7 flowing toward a transducer 2, for reception, at a sensor probe 3 arranged in the bottom part of a flow passage 4, the phase of a signal which is inphase is by +90 deg. different from that of a signal which is at a quadrature phase. On the other hand, in the case of a fluid which flows to its opposite direction, it is confirmed that the phase of the signal which is inphase is by -90 deg. different from that of the signal which is at the quadrature phase. By this invention, even when the phase difference between the signal which is inphase and the signal which is at the quadrature phase is neither +90 deg. nor -90 deg. anticipating a prescribed error value, their spectral components are regarded as noises, they are weighted by 0, and they are removed before a later computing operation. Consequently, an average flow velocity which is found by the computing operation has a high-reliability and high-accuracy value which does not contain any noise components.
